The TrueCrush™ test is a new, patented testing procedure for determining the actual performance of a proppant used in hydraulic fracturing.

In contrast to the API Crush Test, the TrueCrush procedure determines the strength of the entire proppant. This yields a result that gives comparable data for:

  • Cost/benefit analysis

  • Permeability/Conductivity estimation

  • Forecast modeling

New Mexico Tech Research Conclusions

After 2 years of research comparing the API test and TrueCrush, New Mexico Tech’s research program (PDRP) concludes:

  • Higher K-values might not always indicate better proppant performance in terms of downhole permeability

  • The size distribution is one of the key factors that controls the proppant’s performance. The API test does not account for size distribution

  • API Crush Test can be easily manipulated to achieve higher K-Values

  • The API test should be replaced by the TrueCrush test to precisely analyze and compare the capabilities of proppants.

  • The TrueCrush Test … values allow for “apples to apples” proppant comparisons for cost/benefit analysis.

  • The TrueCrush Test data … reveals that the permeability reduction % (and permeability) due to the applied crushing pressure and the TrueCrush EWS are strongly correlated. Because of this strong connection, (TrueCrush) EWS values will assist with decline curve and future reservoir performance forecasting.

  • The implementation of the TrueCrush Test promises to maximize well performance, improve cumulative well output, and enhance decline curve forecasting.
